现有CheckBox控件显示的自定义CheckBox控件 [英] Custom CheckBox Control Shown Over Existing CheckBox Control

问题描述

大家好，



我使用on paint事件创建了一个自定义复选框。这很好用，但是，我的自定义图像复选框显示在现有复选框上。有没有办法让我只隐藏复选框的方框，但保留我的复选框图像？



这是我的代码：

Hi Guys,

I have created a custom checkbox using the on paint event. This is working nicely as it should however, My custom image checkbox is displayed over the existing checkbox. Is there a way for me to hide just the box of the checkbox but keep my "Checkbox" image?

Here is my code:

public void CheckBox_Checked(object sender, PaintEventArgs e)
        {
            CheckBox chck = sender as CheckBox;
            if (chck.Checked)
                e.Graphics.DrawImageUnscaled((Properties.Resources.CheckboxChecked), 0, 0);
            else if (chck.Checked == false)
                e.Graphics.DrawImageUnscaled((Properties.Resources.CheckboxUnchecked), 0, 0);
        }

这个调用如下：

and this gets called as follows:

CheckBox1.Paint += new PaintEventHandler(_customControls.CheckBox_Checked);

推荐答案

你必须从控件中覆盖OnPaint-Method - 也许不用调用base-method。

You have to override the OnPaint-Method from the control - perhaps without calling the base-method.
